According to the company, the thing that is most notable about the N400 and N600 is the fact that they “add liquid cooling support at even the mini tower level to make it easier to access and use for all.”

“With the addition of the N400/N600 series cases joining the existing N200, the N Series stands apart from the competition. It does so with a full array of exciting options that have been designed specifically with cooling performance in mind, especially liquid cooling,” reads the press release. “Its full mesh front panels and well-ventilated layout provide for a more abundant flow of air throughout the case. Fully embracing liquid cooling, N400/N600 each support liquid cooling throughout the case.”

“N400 / N600 both have well-placed support for a 240mm radiator on the right-side of the case. Ensuring that no component will go without much needed airflow, N400 supports up to 8 fans while the N600 supports up to 10 fans. Both support long graphics cards (N400 – 320mm / 12.6in, N600 – 430mm / 16.9in).” Cooler Master also told us that the N600 supports 280mm radiators at the top of its chassis as well.

Where the 12.3-lb N400 supports up to three SSDs and up to eight HDDs, its 17.8-lb cousin has enough room for up to SSDs and seven HDDs. Both cases come with two USB 3.0 and as many USB 2.0 ports.
